Abstract

A program recording/playback apparatus for easily recording/playing back a program that matches a common preference between multiple viewers is provided. A recording/playback apparatus 100 obtains program recommendation information from a server apparatus 300, and retrieves program recommendation information from within. Based on these two pieces of program recommendation information, the recording/playback apparatus 100 generates and combines two search formulas, to generate one search formula. The recording/playback apparatus 100 then identifies one or more programs that satisfy the conditions shown by the one search formula, within EPG data extracted from received broadcast waves, thereby generating program presetting information. The recording/playback apparatus 100 generates a recorded program table based on the generated program presetting information, and displays the recorded program table. The recording/playback apparatus 100 then receives a user'"'"'s selection indicating one or more of the programs shown by the recorded program table, and reads and plays back the selected programs.
